Newton's Cradle

This morning I decided that I wanted to try using the Newton’s cradle thing to show rotational movement, but it was tangled so I’ll just have to explain it. The force of weight increases and decreases the velocity as it moves up or down the curve giving it a tangential acceleration at certain points of the curve. Tension then counteracts weight and pulls the ball radially inward which is weakest at the apex of each side and strongest at the bottom of the rotation. When it strikes another ball the ball transfers its energy this continually happens until the final ball is given force and velocity to travel forward into a circular path. This is a very basic view on how Newton’s cradle works but its essentially conservation of energy and circular motion. This is a picture of something suspended by a strap moving in a circular path, tension up and weight down. It follows the circular path drawn.
